As a result of research for about 10 years in the JSC “SSC RF - IPPE”, OKB “Hydropress“, “Kurchatov Institute”, NIKIET with water cooled reactors with SCP with thermal and fast neutron spectra. Since 2006 “SSC RF - IPPE” and OKB “Hydropress” are working together to conceptual design WWER-SCP single-loop NPP with coolant with fast-resonance neutron spectrum capacity of Ne = 1700 MWt. This Rector has been acknowledged as the prospect of WWER technology with the ability of a transition to the use of MOX-based (U-Pu-Th) fuel and the closed fuel cycle. State Corporation “Rosatom” recognized this trend as an innovative system and signed an agreement on Russia’s participation in the GIF towards SCWR. There is a possibility of using reactors WWER-SCP with a quicklyresonant spectrum of neutrons capacity from 0,3 to 30 MWt for nuclear stations of low power is considered. Results of neutron-physical calculations of fuel cycles with MOX-fuel from oxide uranium and plutonium with possible duration of campaign from 2 till 20 years are presented. Preliminary results of calculations weight-dimensional characteristics in comparison with others offered NPP the specified appointment are resulted. The received results can be used at a substantiation and development of the concept of the developed reactors cooled by water at supercritical parameters, the big capacity for the future atomic.
